Thanks. I think I knew this years ago while spending my off-work hours delving deeper into programming language history and theory, but most of that info is now lost from disuse. Like I said to your sibling post, I see the semantic comparisons, I just don't get calling it a "lisp variant", unless we're going to call every language with somewhat similar or derivative semantics but wildly different syntactical structures and additional semantic constructs lisp variants as well. With that, distinction between languages (primarily for conversation and discussions) becomes virtually non-existent as we could probably come up with a half dozen categories that all languages fall under.
